The thrombogenic effects of activation of blood coagulation are amplified by stasis and counteracted by rapid flow.

12 15 16 17 18 These cytokines stimulate endothelial cells to synthesize tissue factor and plasminogen activator inhibitor-1 and lead to a reduction in thrombomodulin, thereby reversing the protective properties of normal endothelium. Blood coagulation can be activated by intravascular stimuli released at a remote site (eg, products of injured or infarcted tissue) or it can be activated locally by vessel wall damage (eg, damage to the femoral vein during hip surgery) or by cytokine-induced nondenuding endothelial stimulation. 13 14 15 Vascular damage contributes to the genesis of venous thrombosis through either direct trauma 9 12 13 15 or activation of endothelial cells by cytokines (interleukin-1 and tumor necrosis factor) released as a result of tissue injury and inflammation. The factors traditionally implicated in the pathogenesis of venous thrombosis are activation of blood coagulation, venous stasis, and vascular injury. The formation, growth, and dissolution of venous thrombi and PE reflect a balance between the effects of thrombogenic stimuli and a variety of protective mechanisms. 10 11 12 Venous thrombi often break off to form PE. 9 They usually form in regions of slow or disturbed flow in large venous sinuses and in valve cusp pockets in the deep veins of the calf (Fig 1 ) or in venous segments that have been exposed to direct trauma. Venous thrombi are intravascular deposits composed of fibrin and red cells with a variable platelet and leukocyte component.

In those instances in which DVT and PE develop as complications of a surgical or medical illness, in addition to the mortality risk, hospitalization is prolonged and healthcare costs are increased. In addition, patients with DVT are prone to recurrent episodes.

In some instances skin ulceration and impaired mobility prevent patients from leading normal, active lives. Patients who survive the initial episode of DVT are prone to chronic swelling of the leg and pain because the valves in the veins can be damaged by the thrombotic process, leading to venous hypertension. 8 Women are a prime target for PE, being affected more often than men.ĭeep vein thrombosis is a major complication in orthopedic surgical patients and patients with cancer and other chronic illnesses. PE is now the most frequent cause of death associated with childbirth.

5 6 7 This number exceeds the number of American women who die each year from breast cancer. 1 2 3 4 It is estimated that each year 600 000 patients develop PE and that 60 000 die of this complication. DVT and pulmonary embolism (PE) most often complicate the course of sick, hospitalized patients but may also affect ambulatory and otherwise healthy persons. Death can occur when the venous thrombi break off and form pulmonary emboli, which pass to and obstruct the arteries of the lungs. DVT occurs in ≈2 million Americans each year.
